GLSA-200710-04 : libsndfile: Buffer overflow

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200710-04
(libsndfile: Buffer overflow)

Robert Buchholz of the Gentoo Security team discovered that the
flac_buffer_copy() function does not correctly handle FLAC streams with
variable block sizes which leads to a heap-based buffer overflow
(CVE-2007-4974).

Impact :

A remote attacker could exploit this vulnerability by enticing a user
to open a specially crafted FLAC file or network stream with an
application using libsndfile. This might lead to the execution of
arbitrary code with privileges of the user playing the file.

Workaround :

There is no known workaround at this time.

Solution :

All libsndfile users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/libsndfile-1.0.17-r1'

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
